What makes 52o different from similar hands?
52o is 12 combos out of the 1,326 two-card hands and ranks number 166 of the 169 starting-hand classes by equity against a random hand. From the small blind, 52o shoves cleanly 0.5bb shallower than 52s (1.5bb against 2bb). From the big blind, 52o calls cleanly 1bb shallower than 52s (2.5bb against 3.5bb). The offsuit version has three times as many combos but gives up the flush equity of its suited twin.
Where can I check other hands like 52o?
The stack pages show the full shove and call charts at each depth, and the hands closest to 52o in strength, along with 52s, have pages of their own. The combos page counts the specific hands that make up 52o and how card removal changes them.
How were the numbers for 52o computed?
Both players hold one of the 169 starting-hand classes, weighted by the pairs of specific hands that share no card, so blockers count. Blinds are 0.5 and 1 with no ante and equal stacks. Each pair of classes is scored with its exact equity over every five-card board, and the solver repeats best responses against the other side's running average until the hands on the edge are made exactly indifferent.
